From wearable towards epidermal computing : soft wearable devices for rich interaction on the skin

Human skin provides a large, always available, and easy to access real-estate for interaction. Recent advances in new materials, electronics, and human-computer interaction have led to the emergence of electronic devices that reside directly on the user's skin. These conformal devices, referred to as Epidermal Devices, have mechanical properties compatible with human skin: they are very thin, often thinner than human hair; they elastically deform when the body is moving, and stretch with the user's skin. Firstly, this thesis provides a conceptual understanding of Epidermal Devices in the HCI literature. We compare and contrast them with other technical approaches that enable novel on-skin interactions. Then, through a multi-disciplinary analysis of Epidermal Devices, we identify the design goals and challenges that need to be addressed for advancing this emerging research area in HCI. Following this, our fundamental empirical research investigated how epidermal devices of different rigidity levels affect passive and active tactile perception. Generally, a correlation was found between the device rigidity and tactile sensitivity thresholds as well as roughness discrimination ability. Based on these findings, we derive design recommendations for realizing epidermal devices. Secondly, this thesis contributes novel Epidermal Devices that enable rich on-body interaction. SkinMarks contributes to the fabrication and design of novel Epidermal Devices that are highly skin-conformal and enable touch, squeeze, and bend sensing with co-located visual output. These devices can be deployed on highly challenging body locations, enabling novel interaction techniques and expanding the design space of on-body interaction. Multi-Touch Skin enables high-resolution multi-touch input on the body. We present the first non-rectangular and high-resolution multi-touch sensor overlays for use on skin and introduce a design tool that generates such sensors in custom shapes and sizes. Empirical results from two technical evaluations confirm that the sensor achieves a high signal-to-noise ratio on the body under various grounding conditions and has a high spatial accuracy even when subjected to strong deformations. Thirdly, Epidermal Devices are in contact with the skin, they offer opportunities for sensing rich physiological signals from the body. To leverage this unique property, this thesis presents rapid fabrication and computational design techniques for realizing Multi-Modal Epidermal Devices that can measure multiple physiological signals from the human body. Devices fabricated through these techniques can measure ECG (Electrocardiogram), EMG (Electromyogram), and EDA (Electro-Dermal Activity). We also contribute a computational design and optimization method based on underlying human anatomical models to create optimized device designs that provide an optimal trade-off between physiological signal acquisition capability and device size. The graphical tool allows for easily specifying design preferences and to visually analyze the generated designs in real-time, enabling designer-in-the-loop optimization. Experimental results show high quantitative agreement between the prediction of the optimizer and experimentally collected physiological data. Finally, taking a multi-disciplinary perspective, we outline the roadmap for future research in this area by highlighting the next important steps, opportunities, and challenges. Taken together, this thesis contributes towards a holistic understanding of Epidermal Devices}: it provides an empirical and conceptual understanding as well as technical insights through contributions in DIY (Do-It-Yourself), rapid fabrication, and computational design techniques.Die menschliche Haut bietet eine große, stets verfügbare und leicht zugängliche Fläche für Interaktion. Jüngste Fortschritte in den Bereichen Materialwissenschaft, Elektronik und Mensch-Computer-Interaktion (Human-Computer-Interaction, HCI) [so that you can later use the Englisch abbreviation] haben zur Entwicklung elektronischer Geräte geführt, die sich direkt auf der Haut des Benutzers befinden. Diese sogenannten Epidermisgeräte haben mechanische Eigenschaften, die mit der menschlichen Haut kompatibel sind: Sie sind sehr dünn, oft dünner als ein menschliches Haar; sie verformen sich elastisch, wenn sich der Körper bewegt, und dehnen sich mit der Haut des Benutzers. Diese Thesis bietet, erstens, ein konzeptionelles Verständnis von Epidermisgeräten in der HCI-Literatur. Wir vergleichen sie mit anderen technischen Ansätzen, die neuartige Interaktionen auf der Haut ermöglichen. Dann identifizieren wir durch eine multidisziplinäre Analyse von Epidermisgeräten die Designziele und Herausforderungen, die angegangen werden müssen, um diesen aufstrebenden Forschungsbereich voranzubringen. Im Anschluss daran untersuchten wir in unserer empirischen Grundlagenforschung, wie epidermale Geräte unterschiedlicher Steifigkeit die passive und aktive taktile Wahrnehmung beeinflussen. Im Allgemeinen wurde eine Korrelation zwischen der Steifigkeit des Geräts und den taktilen Empfindlichkeitsschwellen sowie der Fähigkeit zur Rauheitsunterscheidung festgestellt. Basierend auf diesen Ergebnissen leiten wir Designempfehlungen für die Realisierung epidermaler Geräte ab. Zweitens trägt diese Thesis zu neuartigen Epidermisgeräten bei, die eine reichhaltige Interaktion am Körper ermöglichen. SkinMarks trägt zur Herstellung und zum Design neuartiger Epidermisgeräte bei, die hochgradig an die Haut angepasst sind und Berührungs-, Quetsch- und Biegesensoren mit gleichzeitiger visueller Ausgabe ermöglichen. Diese Geräte können an sehr schwierigen Körperstellen eingesetzt werden, ermöglichen neuartige Interaktionstechniken und erweitern den Designraum für die Interaktion am Körper. Multi-Touch Skin ermöglicht hochauflösende Multi-Touch-Eingaben am Körper. Wir präsentieren die ersten nicht-rechteckigen und hochauflösenden Multi-Touch-Sensor-Overlays zur Verwendung auf der Haut und stellen ein Design-Tool vor, das solche Sensoren in benutzerdefinierten Formen und Größen erzeugt. Empirische Ergebnisse aus zwei technischen Evaluierungen bestätigen, dass der Sensor auf dem Körper unter verschiedenen Bedingungen ein hohes Signal-Rausch-Verhältnis erreicht und eine hohe räumliche Auflösung aufweist, selbst wenn er starken Verformungen ausgesetzt ist. Drittens, da Epidermisgeräte in Kontakt mit der Haut stehen, bieten sie die Möglichkeit, reichhaltige physiologische Signale des Körpers zu erfassen. Um diese einzigartige Eigenschaft zu nutzen, werden in dieser Arbeit Techniken zur schnellen Herstellung und zum computergestützten Design von multimodalen Epidermisgeräten vorgestellt, die mehrere physiologische Signale des menschlichen Körpers messen können. Die mit diesen Techniken hergestellten Geräte können EKG (Elektrokardiogramm), EMG (Elektromyogramm) und EDA (elektrodermale Aktivität) messen. Darüber hinaus stellen wir eine computergestützte Design- und Optimierungsmethode vor, die auf den zugrunde liegenden anatomischen Modellen des Menschen basiert, um optimierte Gerätedesigns zu erstellen. Diese Designs bieten einen optimalen Kompromiss zwischen der Fähigkeit zur Erfassung physiologischer Signale und der Größe des Geräts. Das grafische Tool ermöglicht die einfache Festlegung von Designpräferenzen und die visuelle Analyse der generierten Designs in Echtzeit, was eine Optimierung durch den Designer im laufenden Betrieb ermöglicht. Experimentelle Ergebnisse zeigen eine hohe quantitative Übereinstimmung zwischen den Vorhersagen des Optimierers und den experimentell erfassten physiologischen Daten. Schließlich skizzieren wir aus einer multidisziplinären Perspektive einen Fahrplan für zukünftige Forschung in diesem Bereich, indem wir die nächsten wichtigen Schritte, Möglichkeiten und Herausforderungen hervorheben. Insgesamt trägt diese Arbeit zu einem ganzheitlichen Verständnis von Epidermisgeräten bei: Sie liefert ein empirisches und konzeptionelles Verständnis sowie technische Einblicke durch Beiträge zu DIY (Do-It-Yourself), schneller Fertigung und computergestützten Entwurfstechniken

Controversial advertising in the UK : its regulation and practitioner ethical decision making

This thesis explores the phenomena of controversial advertising, its regulation, and the ethical dimensions of its practice in a UK. context. The £19bn advertising industry is a major contributor to the British economy, helping to stimulate consumer demand, market competition and employment (IPA, 2012). Despite these benefits, advertising is often criticised for its negative social consequences. Controversial advertisers utilise content or tactics that breach acceptable standards of society (Harker et al., 2005). Controversial advertising practices include: shocking, offensive or distressing content or tactics (Waller et al., 2005); deceptive or misleading advertising claims (Preston, 1996); or harmful social consequences (Pollay, 1986). The UK advertising industry use self-regulation via voluntary codes of practice to maintain acceptable standards; address stakeholder complaints and forestall government intervention (CAP, 2012). Before advertising is placed, media clearance and pre-vetting procedures are also common. However, despite these controls, over 25,000 complaints are received by the Advertising Standards Authority (ASA) every year and on average 2,500 campaigns annually are found in breach of the code (ASA, 2012). This raises questions as to the ethics of controversial advertising practice and the effectiveness of its regulation. This research employs exploratory interpretive methods to makes sense of practitioner ethical decision making (EDM) involved in creating, pre-vetting and regulating controversial UK advertising. New findings highlight the importance of proactive clearance rather than post-complaint regulation. The code of advertising represents a fluctuating line to be pushed at, rather than acting as a moral brake on malpractice. Practitioner EDM is built from the collective interactions of actors, not the actions of individual decision makers or organisations, thus advertising practitioners become myopic to their stakeholder responsibilities. The thesis presents a new 360 degree model of the advertising process from creation through to regulation. The research has important implications for academic, marketing and advertising and regulatory practitioners

Improvisation and Social Aesthetics

Addressing a wide range of improvised art and music forms—from jazz and cinema to dance and literature—this volume's contributors locate improvisation as a key site of mediation between the social and the aesthetic. As a catalyst for social experiment and political practice, improvisation aids in the creation, contestation, and codification of social realities and identities. Among other topics, the contributors discuss the social aesthetics of the Association for the Advancement of Creative Musicians, the Feminist Improvising Group, and contemporary Malian music, as well as the virtual sociality of interactive computer music, the significance of "uncreative" improvisation, responses to French New Wave cinema, and the work of figures ranging from bell hooks and Billy Strayhorn to Kenneth Goldsmith

Making scenarios more worthwhile: orienting to design story work

Increased complexity in contemporary design work has led designers to place greater dependence on the use of story and narrative. Though many consider story and narrative a fundamental part of design, use continues to present challenges and efficacy is poorly understood. With regards to use, challenges stem from a lack of support in directing strategic conversations towards getting the right stories and to getting stories right. With regards to efficacy, poor understanding stems from a lack of research and a corresponding lack of unifying theory. Scenario research represents the largest body of knowledge on the use and efficacy of story and narrative in design. Yet, scenarios are characteristically narrow in scope and their descriptions typically thin. Scenario research is in decline, and what theory exists is neither extensive nor extensible. Nevertheless, scenarios serve as a starting point for this research, with questions posed about how designers work with story and narrative, and how, in turn, story and narrative work for designers. To explore these questions epistemological, philosophical and theoretical positions are taken up and these underpin a Research into/through/for Design methodology. A series of self-reflective experiments lead to the creation of novel narrative resources and approaches, which empirical studies expose to a range of increasingly challenging settings. Findings from these studies show that narrative resources coupled with resource-based approaches provide targeted support for cognitively challenging aspects of story work. Furthermore, outcomes from a programme of critical analysis provide insights into how story, narrative and narrative resources work for designers. Contributions to knowledge are made in three areas: first, in the area of design practice in relation to narrative resources and approaches to story work; second, in the area of design theory in relation to realistic approaches to method innovation; and third, in the area of research practice in relation to aids to visual analysis

UNDERSTANDING IDENTITY, POWER, AND USE OF SPACE OVER TIME WITHIN HOUSEPIT 54, BRIDGE RIVER SITE (K’ETXELKNÁ’Z), BRITISH COLUMBIA

This research examines cultural change and continuity as embodied within a singular multi-generational housepit (Housepit 54) located within the Bridge River site (K’etxelkná’z) in the Mid-Fraser Canyon, British Columbia, Canada. Previous research has highlighted the distinctive differences between Bridge River 2 and 3 time periods wherein the village was faced with dramatic population growth and climate change. These pressures crafted a Malthusian ceiling-type event which corresponded with the emergence of persistent institutionalized inequality. This research aims to illuminate issues of gender, kinship, social identity, and household social relationships in order to highlight how macro-scale cultural change is evinced in micro-scale space-use and activity patterns. This research examines how such a drastic restructuring of the sociopolitical realities within the Bridge River village (K’etxelkná’z) interfaces with interpersonal identity and cultural evolution at the household level

Amrit Singh and the Birmingham Quean: fictions, fakes and forgeries in a vernacular counterculture

For a literary critic preparing a scholarly edition of a text like this within an epistème that disparages the theory underpinning it for being tainted with the gestural idealism of 1968 and the neon-glare of 1980s high postmodernism, the crucial question is how to reconcile the commitment to authenticity ingrained in historicist textual studies (perhaps the critic’s only viable disciplinary inheritance) with the author’s implicit antagonism to any such quietist approach. The encounter inevitably becomes a battle of wills. In the course of the current project, this theoretical struggle escalates exponentially as doubts concerning the authenticity (and indeed the existence) of both writer and manuscript are multiplied. If a thesis can be retrospectively extrapolated from this project, it is the argument that fiction is demonstrably a tractable forum for research in the Arts and Social Sciences: all the more tractable for its anti-authenticity. The critic’s loss is the novelist’s gain. Specifically, in this case, the faithful historian of late twentieth century literatures, languages and cultures can solve the key dilemma of the subject by working under the auspices of Creative Writing. Only in this way can justice be done to the most cogent intellectual trend of the posmodern period (perhaps its defining feature): one that revelled in its own pluralities, ambiguities and contradictions, and resisted all the unifying, teleological models of ‘history’ that had been implicated in the century’s terrible ‘final solutions’. In other words, only fiction can tell the history of a culture that rejects that history. If this means condoning forgery… so be it
